My ford has been in our family ever since it was made but my Dad and I put a new engine and transmission in about 6 years ago. We had it in storage until here recently my Dad wanted me to have it for nostalgia. I don't drive her alot but i do start her up and let her run for a little while. I needed to go to the local store to grab some stuff and I started her up and she started dying so i pressed on the gas she started running on her own after that but then popped out of the muffler and it sounded like a shotgun? I put gas cleaner in and have bought a fuel pump and had the oil changed. I also bought new spark plugs. Is it the carburetor or is the timing off.....
